Title: Vertically adjustable vent cover having venturi cone
Inventor: CRIDER BRIAN D
IPC: B60H1/26
Filed: 1994-11-21
Abstract: A vent cover (10) for a vehicle (14) equipped with a roof vent (12) is raisable and lowerable from within the vehicle by rotating a crank (66). The cover includes a dome (20) formed by a top wall (22), sidewalls (26) that depend from the top wall, and a venturi cone member (33) secured to an underside of the top wall. A vent base (34) mounted to the roof of the vehicle has upstanding sidewalls (36, 38). The cooperative shape of the venturi cone member, the walls that depend from the top wall of the dome, and the upstanding sidewalls of the vent base creates a constricted area above the upstanding sidewalls. The construction forces the air molecules to flow at a high rate of speed, creating a venturi effect that efficiently pulls stale air, smoke fumes, and the like out of the vehicle.
Patent CA-2173948-A1 (CA)
Title: Synchronizing circuit arrangement
Inventor: BUHRGARD KARL SVEN MAGNUS
IPC: H04L12/70
Filed: 1994-10-03
Abstract: The invention relates to a synchronizing circuit arrangement included in a multiplexing/demultiplexing unit which receives a bit stream coordinated to a data pocket. The bit positions and values within a predetermined part of a consecutive bit sequence of each transmitted data packet are constantly selected so that a predetermined check calculation will give a predetermined value (for instance "O").  A consecutive bit sequence corresponding to the predetermined part of a consecutive bit sequence and belonging to respective received data packets is evaluated in order to establish the extent to which the check calculation gives the predetermined value.  When agreement is found, it is assumed that the boundary between two closely adjacent data packets is established via the bit sequence of the predetermined part of a consecutive bit sequence.  Each incoming bit stream is synchronized through the medium of a control block or control logic, by inserting a time delay corresponding to synchronism into a series-parallel converter for respective bit stream. The synchronized, parallel-format bit streams can be delivered via the control block or control logic to a memory which delivers the bit stream to the outgoing connection via buffer circuits and a parallel-series converter.

Filed: 1995-11-14
Abstract: A catalyst unit is constructed by alternately stacking rectangular catalyst elements (1) formed by cutting catalyst support plates coated with a catalytic material and having ribs (2) inclined at 45° to one specified side edge (1a) of each thereof, and those turned upside down in a case, and the catalyst unit is disposed in a gas passage with the ribs (2) of the catalyst elements (1) inclined at an angle greater than 0° and smaller than 90° to the direction of the gas flow (6). When the catalyst unit comprising the catalyst elements (1) coated with a denitrating catalyst is placed in the gas passage, the ribs (2) of the catalyst elements (1) blocks the gas flow (6) and generate turbulent currents on the downstream side thereof to promote the contact of ammonia and NOx contained in the exhaust gas with the catalyst. When the gas flow (6) is disturbed, the thickness of laminar films covering the surface of the catalyst elements (1) is reduced, so that ammonia and NOx can be easily diffused and the catalytic activity can be enhanced. The catalyst elements exhibits their catalytic abilities effectively without entailing significant pressure loss in the gas flow.

Title: Fuel cell with ceramic-coated bipolar plates and its production
Inventor: JANSING THOMAS
IPC: H01M8/124
Filed: 1995-11-30
Abstract: In a high-temperature fuel cell with a solid electrolyte, the solid electrolyte (44) is mounted between metal flanges (30, 30') whose surface is at least partially coated with stabilised zirconium oxide (51, 52) or a similar gas-tight ceramic material with a crystalline structure that solidly adheres to the flanges. This coating narrows the gap between the flanges at the edge of the fuel cell and enables this narrow gap to be filled with a solder glass green foil (53) or similar soldering material that laterally seals the fuel cell in a gas-tight manner when the fuel cell is assembled. The flanges are also insulated from each other.

Abstract: The present invention relates to an electronic-money collecting system capable of returning a lost IC card used as an 'electronic purse' to the owner of the lost IC card or an institution issuing the lost IC card with a high degree of efficiency without giving a troublesome load to the lost-IC-card finder or the institution issuing the IC card. When a lost IC card storing money data representing an amount of electronic money is found, the found IC card is entered into a terminal installed at places such as a bank or other public institution. At that time, information read out from the IC card is transmitted to a central apparatus by way of a communication line. At the central apparatus, a storage unit is searched for information on the legitimate owner of the IC card, i.e. information for contacting the owner. The owner of the lost IC card is then notified of the implementation of processing to collect the IC card by telephone, through the post or through an electronic mail using a communication means.      In order to increase the rate of collection of lost IC cards, a lost-IC-card finder is given reward money which is set in accordance with the amount of money recorded in a found IC card. In addition, when an attempt made by a lost-IC-card finder to illegally draw money from a found IC card is detected, information on the lost-IC-card finder who makes the attempt to draw money from the found IC card is recorded, allowing the abuse of a found IC card to be detected early.

IPC: F01D17/10
Filed: 1997-06-24
Abstract: A bleed apparatus (34) for a gas turbine engine (10) is positioned in the duct (16) between a low pressure compressor (14) and an intermediate pressure compressor (18). The bleed apparatus (34) comprises a plurality of circumferentially spaced bleed apertures (38) and a plurality of pivoted (42) bleed doors (40) which move between a fully open position and a fully closed position. Each bleed door (40) has an independent actuator (44,46) and the actuators (44,46) operate to fully close or open the bleed doors (40) in unison. Each actuator (44,46) comprises a hydraulically operated piston (46) and a cylinder (44) which ensures uniform closing and sealing and the remaining bleed doors (40) operate if one seizes. The bleed apertures (38) have radially extending side walls (72,74) which control the bleed air. The first and second walls (72,74) prevent the bleed air flowing circumferentially from the bleed aperture (38) until the bleed doors (40) have opened a predetermined amount to provide a continuously increasing bleed area as the bleed doors (40) move towards the fully open position.
